  Elektrische Leuchtröhre für Niederspannung. 



   Die Erfindung bezieht sich auf eine rohrför'mige Kathodenglimmlichtlampe in Form eines Buchstabens,   einer Ziffer oder einer Figur und mit Elektroden, deren Länge grosser   ist als diejenige des die Lampe bildenden Rohres und die aus mindestens zwei voneinander getrennten, miteinander parallelen, kon- zentrisch gewickelten, schraubenlinienförmigen Drähten gebildet sind. 



   Gemäss der Erfindung stützen sich die Elektroden an der Innenwand des Rohres ab, wodurch jede besondere Halterung in Wegfall kommt. Die Elektroden werden zweckmässig eckig gewickelt, so dass sie sich mit ihren Ecken an die Rohrwand anschliessen.. 



   In den Fig. 1-4 ist ein   Ausführungsbeispiel   der Erfindung dargestellt. 



   In dem Rohr 1 aus gewöhnlichem oder mattiertem Glas sind zwei konzentrisch gewickelte schraubenlinienförmige Elektroden 2 und 3 vorgesehen, welche bei 4 und 5 aus dem Rohr herausgeführt und über einen Vorschaltwiderstand an das Netz angeschlossen sind. 



   PATENT-ANSPRÜCHE :
1.   Gas- oder dampfgefüllte rohrförmige Kathodenglimmlichtlampe   in Form eines Buchstaben, einer Ziffer oder einer Figur und mit Elektroden, deren Länge grösser ist als diejenige des die Lampe bildenden Rohres und die aus mindestens zwei voneinander getrennten, miteinander   pallallelen,   konzentrisch gewickelten, schraubenlinienförmigen Drähten gebildet sind, dadurch gekennzeichnet, dass

  Electric tube for low voltage.



   The invention relates to a tubular cathode glow lamp in the form of a letter, a number or a figure and with electrodes whose length is greater than that of the tube forming the lamp and which are concentrically wound from at least two separate, parallel, concentric , helical wires are formed.



   According to the invention, the electrodes are supported on the inner wall of the pipe, so that any special holder is no longer required. The electrodes are expediently wound at an angle so that their corners connect to the pipe wall.



   An embodiment of the invention is shown in FIGS. 1-4.



   In the tube 1 made of ordinary or frosted glass, two concentrically wound helical electrodes 2 and 3 are provided, which are led out of the tube at 4 and 5 and connected to the network via a series resistor.



   PATENT CLAIMS:
1.Gas- or vapor-filled tubular cathode glow lamp in the form of a letter, a number or a figure and with electrodes, the length of which is greater than that of the tube forming the lamp and which are formed from at least two separate, parallel, concentrically wound, helical wires are characterized in that
